What is liga hd?

As an AI language model, I cannot guarantee the accuracy or existence of "liga hd" as it could be referring to different things. It would be helpful to provide additional context or specify which "liga hd" you are referring to.

However, if by Liga HD you are referring to a sports channel, there are several channels with this name broadcasting different sports. Some of them include Liga HD in Spain and Liga HD in Latin America, which broadcast football/soccer matches from the Spanish La Liga. There are also channels named Liga HD in Portugal that broadcast football matches from the Portugal Primeira Liga.
